grub problem after installation.


Hello,

my Fedora16 has been installed and was working properly. But now the grub menu doesn't appear and enters the command-line environment and prints this :
Code:
GRUB loading 
Welcome to GRUB!
error: no such partition.
entering rescue mode...
grub rescue>
and as far as I know (by googling) I should recover my grub by fedora CD-ROM and I did,

but while entering the rescue mode (before starting anaconda intaller) I've seen this message:

Code:
systemd: failed to fully start up daemon in rescue
it seems to arise a problem by admitting this, isn't it?
and then I've choosed my language and continue to get shell screen,

but I can't "chroot /mnt/sysimage" this error appears:

Code:
chroot failed to run command bin sh' exec format error
and by googling I've found that, that's why my installed-fedora and the CD-ROM used for rescue aren't on the same system (32bit or 64), but this one is the same media which I used for installation!

Would anyone please help me?

Looks like booting with a 32-bit OS but the systtem on the hard drive is 64-bit. You could check this by booting off the CD, mounting the hard drive partition containing /boot, and verifying that the vmlinuz file in /boot matches the vmlinuz file on the CD (run the command uname -r in the terminal window)

Thanks!

I changed the type of OS into 64-bit, then it was solved.
But I still have a question, I should say that the previous problematic CD-ROM which I used for rescuing was exactly the same which was used for installation, is it possible that a 32-bit-Fedora16 CD-ROM installs a 64-bit system on my hard drive?

Thanks.

I don't believe that is possible. I don't believe there are any 64-bit goodies on the 32-bit CD-ROM. I have a 32-bit Fedora-15 install on a flash drive, and there are no 64-bit rpms installed.
